PTEROMY Navy Lightweight Sleeping Bag for Adults — 2.1 m, Machine Washable, Water-Resistant 3-Season with Compression Sack

PTEROMY's navy adult sleeping bag is a lightweight, water‑resistant 3‑season sleeping system that packs small, washes in a machine without clumping, and fits adults up to 7ft tall.

Whether you're backpacking a weekend, car camping with friends, or keeping a compact emergency blanket in your vehicle, this sleeping bag balances warmth, portability and everyday practicality. It uses Hollowfiber fill with double S stitching to protect loft and thermal performance, a soft spun‑cotton lining for comfort, and a compression sack for compact transport. The design also includes practical features such as an adjustable drawcord hood, inner pocket and a bottom zipper for ventilation when nights warm up.
